Add SERVICE_INTERFACE and SERVICE_META_DATA constants to RecognitionService,
to be used by anyone implementing a voice recognition service. Also define
a new <recognition-service> styleable to be used in such service's metadata
xml.

Still to do: Change VoiceSearch's GoogleRecognitionService to respond to this
intent, and actually use this intent instead of ACTION_RECOGNIZE_SPEECH here
in RecognitionService.
